A couple of months ago, I made a video about an adapter to extend the steerer tube by 50mm (2").
Steerer Tube Too Short? • Steerer Tube Too Short?
However, it’s missing the functionality of a headset cap (top cap) for adjusting the preload on the headset bearings, what it exactly means is that you could have back and forth play if the headset is loose, or your handlebar would not turn freely if it’s too tight, so tightening your headset bearings to the correct amount of preload is very important.
In this video, I’ll show you how I made the adapter clamped to steerer tube and then put in the Hope Head Doctor (adjustable star fangled nut) to the adapter.
You need 2 things:
1x M8 bolt, 4" x 1.125"
1x M10 flange nut
Put in the M10 flange nut into the adapter, nut facing downward, it should stuck in bottleneck. Use the short M8 bolt and screw it to the wedge, now put the adapter into the steerer tube and tighten the bolt. Make sure it is tight and solid before going to the next step.
Now you only have to put in the star fangled nut. I used Hope Head Doctor for a superior top cap and star nut system. (Easier to remove)
If you are having a hard time fitting in, insert a bolt and hammer it down.
And finally, put back everything and install the headset cap.
Remember to put in the correct amount of preload on the headset bearings, then tighten the stem bolts at the end.
Like I mentioned before, if the headset is too loose, you could have back and forth play, and if it’s too tight, your handlebar would not turn freely, so make sure you put in the right amount of preload on the headset bearings.
